Abstract: A system is disclosed for supporting dynamic spectrum access in wireless networks. The system includes at least one cognitive base station configured to communicate over at least one licensed carrier. The system further includes a spectrum accountability server operably coupled to the at least one cognitive base station. The spectrum accountability server is configured to manage spectrum leases to dynamic spectrum access carriers according to a set of spectrum access rules, and the spectrum accountability server may further be configured to dynamically change the spectrum access rules in response to spectrum usage policies or spectrum availability, or both. A wireless communication network and related method for providing dynamic spectrum access to secondary users of a wireless network are also disclosed herein.

Abstract: An airborne wireless communication system includes circuitry configured to access information describing a configuration of a terrestrial wireless communication base station that has become disabled. The terrestrial base station is configured to implement wireless communication between wireless devices located within a geographical area and a network when the terrestrial base station is not disabled. The circuitry is further configured, based on the information, to configure the airborne station to have the configuration of the terrestrial base station. An airborne communication method includes answering a 911 call from a terrestrial cellular wireless phone using an airborne wireless communication system.

Abstract: A method (200, 300) of managing mobile context and advertising over a communications network based on the context. The method includes identifying (204) a context (146, 152) associated with a communication sent to or received by a remote unit belonging to the user group of remote units. The method also includes determining (212) whether the identified context is associated with one or more advertisements by querying correlation data (144) to identify advertisements having context that correlates to the identified context. When the identified context is associated with one or more advertisements, the method includes transmitting (214) the one or more advertisements to at least one remote unit belonging to the user group.

Abstract: A system (2100, 2400) for taking network elements (112) off-line includes a memory (1806) for storing a record (1802) of a number of calls being handled by a first network element (112) over a period of time and a processor (1804) communicatively coupled to the memory (1806), where the processor (1804) is used for setting a threshold value based on the record (1802), monitoring in substantially real-time, a number of calls being handled by the first network element (112), and comparing the number of substantially real-time monitored calls being handled by the first network element (112) to the threshold value. The system also includes a switch (1816) communicatively coupled to the processor, where the switch (1816) is used to take the first network element (112) off-line if the number of substantially real-time monitored calls being handled by the first network element is below the threshold value.
